I was thinking on doing an oil change in my truck with synthetic motor oil.
Has anyone really noticed a difference on the way it runs and gas mileage?
I understand the pros and cons of both,but really---is it that much better for the price?

Mastevt

be careful! syn. if used in an older high mileage engine, can induse oil consumption. It is a thinner oil, and makes the internals of the engine sliker, and thus more oil can get by the rings on the pistons and down thru the seals on the valve stems.

Like what Mastevt make sure that your engine is able to use that oil one way to check that is to check the owners manual or call a place where they do oil changes and they should tell you and from what ive noticed it does make a difference and it is worth the extra money.

I've been using Mobli 1 Synsthetic for 11 years. I started with using it with 1995 Toyota Tacoma. Sometime in November of 1998 I was on my way home from deer hunting, and my head gasket blew, but I didn't know it, until I got home. My truck was towed to Toyota I still had a warrenty, a week later I went to pick up my truck, the service manager asked me what oil I used, and told him Mobil 1, he said that my pistons/rods looked like brand new, that put a smile on my face knowing that Mobil 1 did it's job, still using it today in my 2005 Toyota Tacoma

I am using Mobil 1 Syn in 3 vehicles. A 91 Ford with 200k a 96 Explorer with 90k and a 2000 Silverado with 135k. You can pay more for oil but its hard to beat the Mobil 1 Syn. None of the 3 leak oil and none of the 3 burn oil. The 96 and the 200 were bought used and started on Syns at 60k and 50k. The 91 was bought new and was started on synthetics at 130k. No problems and I would reccomend to anyone.

I have had great luck with Amzoil synthetic oil in my trucks and minivan. After switching over I got 2-3 mpg better. In fact, I'll be switching to the Amzoil transmission fluid tomorrow in my Ranger 4x4.

As far as switching to a synthetic oil, it will not hurt the engine by no means. But say you have 150,000 miles on the engineor 5,000 it will not cause nothing but if you have an oil leak, even it it only drips once per day, the synthetic will make the leak worse as the particles in the oil break up. So no there will be no problem caused but it will bring up existing that you didn't know about. Hope that helps.

Owning a parts store i here my fair share but for the record all oils are going to be synthetic or semi-synthetic eventually. the ones that wont will be the house brands, they will keep a non syntec. the best thing is to put in a qt of lucas oil stabalizer with every oil change for example if your vehicle takes 5qts put in 4 and 1 of the lucas. and lucas is so good that when you change your oil the next time you can still feel the lucas in the oil it will not break down.
